What This Category of Data Looks Like
Data sources for this category include special equipment safety supervision systems, inspection and testing institution systems, user account ledgers, and operator certificate databases. Data is updated monthly. Commonly processed documents include use registration certificates, periodic inspection reports, maintenance records, hidden danger rectification notices, accident reports, and operator certificates. Documents contain fixed fields such as equipment number, inspection cycle, maintenance date, hidden danger content, and operator qualification number. Standardized identifiers include units, counts, date formats, and qualification levels.
Constraints Imposed on Document Parsing and Chunking
Document formats vary widely across sources. Structured Excel account ledgers, fixed-format PDF reports, and semi-structured handwritten rectification records are all common. Parsing tools must support field extraction across multiple formats. Monthly batch-updated documents have large volumes. Parsing duration and file upload limits must be controlled to prevent batch task interruptions. The integrity of core fields such as inspection cycles and equipment numbers directly affects supervision workflows. Chunking operations must not break logical relationships between fields. Doing so will cause errors in subsequent verification steps. Parsing errors in high-risk supervision documents may lead to deviations in subsequent workflows. Parsing accuracy and data integrity must be ensured.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of continuously associated fields such as equipment numbers and inspection cycles in special equipment documents, preventing field breakage after splitting |
chunkSplitter | Split by paragraph + semantic meaning | Adapts to documents with process logic such as maintenance records and hidden danger rectification notices, preserving contextual associations |
customPdfParse | Enable structured parsing mode | Adapts to PDF documents with fixed tables such as periodic inspection reports and use registration certificates, accurately extracting fields within tables |
UPLOAD_FILE_MAX_SIZE | 100 MB | Matches the conventional size limit of account ledgers and report files imported in monthly batches |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the parsing duration of large accident reports and batch account ledgers, preventing timeout interruptions |
chunkSettingMode | Manual configuration | Adjust chunking parameters for different document types, adapting to the diverse formats of special equipment documents |
Three Common Misconfigurations
- Symptom: A large number of empty fields appear in the parsing result after uploading an Excel maintenance account ledger. Cause: Structured parsing configuration for table documents is not enabled, and Excel cell field extraction rules are not adapted.
- Symptom: A timeout error is returned when parsing a single large periodic inspection report. Cause: The
PARSE_FILE_TIMEOUT_SECONDSsetting value is lower than the actual required parsing duration, and the processing rhythm for large files is not matched. - Symptom: The start and end dates of the inspection cycle are split into two separate chunks after chunking. Cause: The
chunkSizesetting value is too small, causing paragraphs containing continuously associated fields to be forcibly split, breaking data logic.
How to Verify the Configuration Is Correct
- Upload a single standard-format periodic inspection report PDF, and check whether core fields such as equipment number and inspection validity period are fully extracted in the parsing result.
- Upload a batch of monthly maintenance account ledger Excel files, confirm that the upload progress has no abnormal interruptions, and that no batch field missing occurs in the parsing result.
- View the chunked text fragments, and confirm that associated fields such as inspection cycle and maintenance date are not split into different chunks.
- Verify the upload limit configuration: upload a test file within 100 MB, and confirm that the parsing process can be completed normally.
